SEOUL, South Korea (AP) -- North Korea is warning of future nuclear and rocket efforts that it says are warranted because of new U.N. sanctions over its third nuclear test.

The statement Saturday from an unidentified Foreign Ministry spokesman builds on a torrent of warlike threats from Pyongyang in the wake of the sanctions, which North Korea says are an indication of U.S. hostility.

The sanction, approved Thursday, target North Korea's ruling class.

U.N. diplomats say the sanctions will hurt leader Kim Jong Un. But others argue they may actually bolster him by allowing officials to whip up anti-U.S. sentiment and direct attention away from government failures.

Pyongyang's statement says "the world will clearly see what permanent position" it will take to "reinforce as a nuclear weapons state and satellite launcher" because of the sanctions.

Engineer found guilty of killing three of his bosses

SAN JOSE, Calif. (AP) -- A Silicon Valley engineer has been found guilty of first-degree murder for fatally shooting three of his bosses as revenge for being fired.

A California jury on Friday convicted Jing Hua Wu of gunning down three executives at a Santa Clara semiconductor startup called Siport on Nov. 14, 2008.

The jury rejected Wu's attorney's contention that Wu was too mentally ill to form the intent to kill when he shot CEO Sid Agrawal, office manager Marilyn Lewis and his immediate supervisor Brian Pugh.

The same Santa Clara County jury must now determine whether Wu was too mentally ill to be held legally responsible for the murders.

If found insane, he would be sent to a state mental hospital. If not, he would be sentenced to life in prison without parole.

That result is likely to bring controversy in Kenya and an almost certain legal challenge from Prime Minister Raila Odinga. Kenyatta needed to break the 50 percent barrier to avoid a run-off with Odinga, but he did so by only 4,099 votes out of more than 12.3 million cast.

Monday's presidential vote was the first since Kenya's 2007 election sparked two months of tribe-on-tribe violence after a disputed election win was claimed by President Mwai Kibaki. More than 1,000 people were killed in attacks that included machetes, bows and arrows and police firearms.

A win by Kenyatta could greatly affect Kenya's relations with the West. Kenyatta faces charges at the International Criminal Court for his alleged role in directing some of Kenya's 2007 postelection violence. His running mate, William Ruto, faces similar charges.A win by Kenyatta could greatly affect Kenya's relations with the West because the candidate faces charges at the International Criminal Court for his alleged role in directing some of Kenya's 2007 postelection violence.
